1) Message boards : AP26 - AP27 Search : Should AP27 be GPU-only? (Message 96328)
Posted 1057 days ago by cromido
I don't know the application extensively, but assuming it runs on OpenCL,
if the server is properly configured, the (GPU) app can also be sent to CPUs, as long as the OpenCL environment is installed.

This way, people could run the program "efficiently" in GPUs (Nvidia, AMD and Intel), but an alternative would still exist, and only one slot would be used.
Furthermore, when I have used OpenCL programs on CPU all available cores were used, so the memory usage would not be prohibitive (1.1GB RAM is indeed a lot, specially for multiple GPUs)

Thank you for the list.

I already knew about the "Primes by Project", but it excluded some SGS primes (it seems now it excludes all n=666666.

I'm looking for a list of all primes found, and, I don't know if it is feasible, but ideally the candidate file (with all the tested numbers and their status (prime/not prime)) would be ideal.

Now that n=666666 search is complete, would it be possible to release the full results, as it was done for TPS 195000 and TPS 333333?

I still can't run either pfgw32, wwwwcl.exe or wwww.exe on my 32-bit Windows XP machine, with a "is not a valid Win32 program" errors. Any tips for troubleshooting?

Trinity (A6-4455M) works:
http://www.primegrid.com/results.php?hostid=419390

And can be completed within the given timeframe.

No, 7670M does not support DP.

Oh, and while you are at it, the runtimes for the short tasks (even if they are growing, a indication of the size is already good) would be very useful information. I think the majority (to not say all) of mobile APU's, for instance, won't be able to complete the short tasks in time even running 24/7.

The first generation of APU (Llano), whose CPU number format is A?-3??? doesn't support DP (if someone wants to try just to be sure, go ahead).

The second generation (Trinity), whose CPU number format is A?-5??? (in desktop) and A?-4??? (in notebooks) supports DP, but I'm not sure on this one. Again, some confirmation is welcome.

The third generation (Richland), whose CPU number format is A?-6??? (in desktop) and A?-4??? (in notebooks) supports DP. The GPU of Trinity and Richland are in the same level, so if one supports it, the other will too, but, again some confirmation is welcome.

To summarize (subject to confirmation, please report), one can run it in APU if it's A?-(>3)???.

On the low power range, the first generation (Brazos), doesn't support DP.

The second generation (Kabini), however, should support DP, but this one I really don't know. If anyone has this APU, please let us know if you can run GeneferOCL.


On the mobile GPU front, 7730M or higher should run it, and then all of the next generation (8???M) too.

8730 or higher also runs GeneferOCL.

But if anyone is actually sucessful (or unsucessful) in running GeneferOCL on their particular card/APU, please say here. An exaustive list would be very helpful.
